[A comparison of submicroscopic changes in the testes of rams after experimental ischemia with findings in orchitis in breeding rams].
Submicroscopic changes in the testes of rams were studied after experimental ischaemia induced by ligature on a. testicularis. The obtained findings were compared with those after traumatic orchitis in breeding rams. Both groups of animals showed marked changes in the germinal as well as Sertoli cells, which were characterized by generalized vacuolization of cell cytoplasm, accompanied by cell caryolysis. The Sertoli cells showed lipid cumulation and glycogen multiplication. The tubule wall had undulated layers. A pronounced reduplication of the lamellar layer of the tubule wall was recorded in the rams with orchitis. The interstitial tissue shows multiplication of collagenous fibres. The findings warn against traumatic injury of testes. The disordered spermiogenesis is irreversible.
